Thomas' older brother, A M Callaway, was my g-g-grandfather, Allen Mason "Mace" Callaway, and gave permission for the marriage, as well as serving as bondsman for his little brother. As the nearest living relative of the said Thomas Callaway I hereby consent to the marriage of the above parties.

Perhaps other family members felt Thomas and Isibelle were too young to marry. They were both barely 18 years old.

The marriage took place on 17 Dec 1876, and Thomas and Isibelle were married for 24 years, until her death on 6 Oct 1900. They had 13 children, and many of their descendants still live in Clark County, AR.
